This program fits two <a class="groops-class" href="fileFormat_variationalEquation.html">inputfileVariational1/2</a> to satellite-to-satellite-tracking (SST) and orbit
observations in a GRACE like configuration. It works similar to <a class="groops-program" href="PreprocessingVariationalEquationOrbitFit.html">PreprocessingVariationalEquationOrbitFit</a>,
see there for details.</p><p>As the relative weighting of the observation types is important complex description of the covariances can be set with
